The vapour pressure of the test item was investigated using isothermal thermogravimetric effusion method according to OECD TG 104 andEC Guideline A.4..The vapour pressure of the substance was found to be：
vapour pressure at 20°C：<=2.8*10-3Pa (<=2.1*10-5 mm Hg)
vapour pressure at 25°C：<=4.4*10-3Pa (<=3.3*10-5 mm Hg)
